Relax all your muscles, especially the grip on the control and your legs. Slight changes in pressures on the controls as small as you can make. The idea is not know you have landed until the collective bottoms.
Do NOT think about the landing itself, especially a smooth touchdown! That will make you anxious, tense, and incline you to rush, especially bad when you start "feeling for the ground" or assume you have touched down.
Concentrate on holding the aircraft in position and slowly descending. If you move off the position stop the descent until you are where you want to land, relaxed with the aircraft motionless again, at which point you concentrate on maintaining position while gradually reducing power.
Landing the aircraft has no difference to hovering except you allow descent. Eventually the descent will result in ground contact and that makes people anxious about that point, which makes the process unnecessarily difficult. It is and should be seamless from the time you hold position until the collective bottoms out.
